    Course List

Dr. Al Moutassem Billah Mahmoud Khair is an Assistant Professor at the College of Dentistry (COD), Ajman University, and the Head of the Department of Basic Medical & Dental Sciences. His major field is Biology, and he teaches both undergraduate and postgraduate students. His M.Sc. and Ph.D. projects focused on studying the effects of ionizing radiation on biological systems at the cellular level, specifically in inducing chromosomal aberrations, polyploidy, cell cycle changes, cell fusion, and chromatin conformation. These studies were conducted both in vivo and in vitro using immunofluorescence microscopy and flow cytometry. In recent years, his research has shifted to the field of Oral Biology. Dr. Khair has authored 16 publications, delivered 9 presentations, secured 5 research grants, and participated in 26 workshops, training courses, and conferences.

Research
  • 1989–1997: He worked as a researcher in the Department of Radio-Biology & Health, Atomic Energy Commission of Syria, and as a part-time lecturer. After his graduation, he continued in the same field, applying similar techniques to study the theoretical and practical aspects of flow cytometry and its use in biological and clinical analyses. The following research projects were carried out: flow cytometric study of chromatin conformation in human lymphocytes of patients with hereditary diseases; flow cytometric study of chromatin conformation and chromosomal aberrations in human lymphocytes after irradiation and hyperthermia; the effect of gamma rays on liver ploidy in mouse embryos using flow cytometry; flow cytometric study of estrogen receptor and DNA content in breast cancer; and the effect of deltamethrin on cell cycle stages during chicken embryo organogenesis, as studied by flow cytometry.
  • 1983–1989: He conducted studies and research for his M.Sc. and Ph.D. projects, which focused on the effects of ionizing radiation on biological systems at the cellular level, specifically in inducing chromosomal aberrations, polyploidization, cell cycle changes, cell fusion, and chromatin conformation. These studies were performed both in vivo (using rats, mice, and guinea pigs) and in vitro (using lymphocytes, V-97, and HeLa cells) with the aid of immunofluorescence microscopy and flow cytometry.
  • In recent years, he has been conducting research in oral biology alongside other faculty members at the College of Dentistry.
